New online traffic map from the Post

Dr. Gridlock today rolls out an upgraded online live traffic tool that aims to make it easier to identify and avoid bottlenecks before you head out, whether it's to the office or a Thanksgiving trip.

The new traffic page, accessible from the Post's transportation portal, shows a real-time map of the region's major roads, color-coded by their current condition (the red, yellow and green need to explanation). Hover over a spot and you'll get current speeds on those roads, down to particular exits.

It's also your point of access to live traffic cameras all around the region.

And in addition to scoping out individual road segments, you can input a particular route. You can even save the route and have alerts directed to your email or mobile device when problems arise.

I have emailed this provider about their lack of some important routes, e.g., US 29 Colesville Road, which are not included. They claim their rationale is that they don't get good data from roads with traffic lights controlling traffic. I think that WaPo should talk to them about addressing these routes also. Potential others 16th Street NW, Georgia, Connecticut, etc.

From Dr. Gridlock: jimmy_mac, just adding one thought to what Michael said, you can still get the traffic camera views for guidance on routes not covered by the color codes if you click on the "Traffic Cameras" tab.

Once you're done with one camera, though, be sure to click "Back to map" rather than hitting your computer's back button, so you can see more camera locations.

(My beef about the cameras generally is that there should be more on the eastern side of the region -- along Route 50, for example, or on Routes 4, 5 and 210.)
